Subject:          ISO-NE’s Preferred Longer-Term Transmission Solution
Cc:                  Planning Advisory Committee (PAC)

NESCOE writes to acknowledge ISO-NE’s selection of proposal A-1 as the preferred Longer-Term Transmission Solution in connection with the March 31, 2025, Longer-Term Transmission Planning (LTTP) Request for Proposals (RFP). The LTTP process allows NESCOE to request that ISO-NE pursue transmission investment through a state-driven, study-based process that evaluates measurable benefits.

NESCOE did not propose an alternate cost allocation for this first LTTP cycle. NESCOE appreciates the significant work that ISO-NE has put into developing and administering the first LTTP RFP. NESCOE looks forward to the next steps in this process, including the lessons learned discussions that will take place later this year.
